Product details
Overview
MSP430F2618TPM from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 116KB+256B flash, 8KB RAM, dual 12-bit DACs, three-channel DMA, 12-bit ADC with autoscan, two 16-bit timers (Timer_A3 and Timer_B7), four USCI modules (dual UART/IrDA/SPI + dual I²C/SPI), and on-chip comparator. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems and portable medical devices.
For engineers reviewing the MSP430F2618TPM datasheet, MSP430F2618TPM pinout, MSP430F2618TPM application, or MSP430F2618TPM equivalent, key selection criteria include its 64-pin LQFP package, 8KB RAM capacity, dual DAC support for analog output generation, 12-bit ADC with internal reference, and wake-up time under 1 µs from standby mode.
Technical Context
The MSP430F2618TPM implements a 16-bit CPU with constant generators and a calibrated DCO enabling sub-1-µs wake-up from LPM3/LPM4. Its peripheral set includes two independent USCI_A modules supporting UART, IrDA, and SPI, plus two USCI_B modules supporting I²C and SPI - all configurable for simultaneous operation.
It integrates a 12-bit ADC12 with eight input channels, internal voltage reference (2.5 V), sample-and-hold, and autoscan; dual 12-bit DAC12 modules with voltage output and synchronization capability; and a three-channel hardware DMA controller that offloads data transfers from the CPU during ADC conversions or USCI transactions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2619TPM | 120 KB + 256 B flash, 4 KB RAM, same peripherals and pinout | Higher flash capacity suits larger firmware with cryptographic libraries or OTA update staging | Select when firmware footprint exceeds 116 KB or when future feature expansion is anticipated |
| MSP430F2418TPM | No DAC12 or DMA modules; otherwise identical flash/RAM and peripheral count | Lacks analog output and hardware-accelerated data movement - unsuitable for DAC-driven control or high-throughput sensor streaming | Select only if DAC and DMA are unused; provides cost reduction where those features add no value |
Compared with MSP430F2619TPM, the MSP430F2618TPM trades 4 KB flash for +4 KB RAM - favoring data-intensive buffering over code size. Against MSP430F2418TPM, it adds DAC and DMA - enabling closed-loop analog control and autonomous sensor data transfer without CPU intervention.

FAQ
What is the maximum operating frequency of the MSP430F2618TPM?
The MSP430F2618TPM supports a maximum system clock (MCLK) frequency of 16 MHz, derived from its calibrated DCO or external crystals (XT2 up to 16 MHz). The CPU executes instructions at 62.5-ns cycle time, enabling deterministic real-time performance for time-critical sensor sampling and control loops within the MSP430F2618TPM architecture.
Does the MSP430F2618TPM support hardware debugging?
Yes, the MSP430F2618TPM includes a full 4-wire JTAG interface (TCK, TMS, TDI/TCLK, TDO/TDI) compatible with TI's MSP-FET and third-party emulators. This enables non-intrusive breakpoints, register inspection, and flash programming - all without consuming device resources or requiring special boot sequences in the MSP430F2618TPM.
How many analog input channels does the MSP430F2618TPM ADC support?
The MSP430F2618TPM integrates the ADC12 module with eight selectable analog input channels (A0–A7), configurable via the ADC12CTL0 and ADC12MCTLx registers. These channels support single-ended or differential acquisition, internal temperature sensor, and VCC/2 reference monitoring - all accessible directly in the MSP430F2618TPM's analog subsystem.
Can the MSP430F2618TPM generate synchronized analog outputs?
Yes, the MSP430F2618TPM includes two 12-bit DAC12 modules (DAC0 and DAC1) with hardware synchronization capability. When enabled, both DACs update simultaneously on a common trigger - essential for generating matched differential signals, stereo audio waveforms, or coordinated actuator commands in the MSP430F2618TPM.
Is the MSP430F2618TPM pin-compatible with other MSP430F261x devices?
Yes, the MSP430F2618TPM in the 64-pin PM package shares identical pinout, electrical characteristics, and peripheral mapping with MSP430F2616TPM, MSP430F2617TPM, and MSP430F2619TPM - enabling drop-in replacement within the same package variant without PCB changes for the MSP430F2618TPM.
